Marischal College is a large granite building on Broad Street in the centre of Aberdeen in north-east Scotland, and since 2011 has acted as the headquarters of Aberdeen City Council. However, the building was constructed for and is on long-term lease from the University of Aberdeen, which still uses parts of the building to house a museum and for ceremonial events. Today, it provides corporate office space and public access to council services, adjacent to the Town House, the city's historic seat of local government. Many Aberdonians consider Marischal College to be iconic of the "Granite City" and to symbolise the zenith of Aberdeen's granite-working industry.

The construction of the modern college building began in 1835, following the demolition of previous buildings on the site, and was completed in its present form in the early 1900s. It is the second largest granite building in the world.[2] Formerly the seat of the Marischal College and University of Aberdeen founded in 1593, the building was retained by the unified University of Aberdeen which was created in 1860 by the merger of Marischal College and King's College. The buildings of Marischal College continued to be used for academic purposes until the mid-20th century and less and less until the early 2000s. During this period they were frequently rebuilt and expanded upon.
